Abstract(in English) | It can be postulated a hypothesis that the categorical judgments of facial expressions are based on the probability density functions of emotional categories in the multidimensional space of physical attributes. The present study attempted to test it by comparing a neural network simulation with a psychological experiment data. In the neural network simulations, we created a 3-layered radial basis function (RBF) network, which has Gaussian basis function in hidden units. The network learned 216 schematic facial expressions of 6 emotions which were obtained from Yamada (1993). As a result, the simulations could judge facial expressions correctly (90-100% correct answers). And we obtained high canonical correlations between the network's performance and the participants' judgment distributions. Thus it can be concluded that the hypothesis described above is supported. |
